8 616T, 616R - Using the Dual-Link Detachable Optical DVI System
4.3 Avoiding Pitfalls During Operation
If any of these problems occur, we recommend the following:
If the display device shows only a black screen:
• Check that all the AC and DC plugs and jacks used by the external power
supplies are firmly connected
• Check that the DVI ports are firmly plugged into the computer and the
display device, and be sure that the transmitter and receiver modules are
correctly plugged into the computer and display device, respectively
• Check if the computer and display are powered on and properly booted
• Reset the system by unplugging and then replugging the transmitter DVI port
or receiver DVI port and then reboot the system
If the screen is distorted or displays noise:
• Check if the graphics resolution is properly set
• Go to Display Properties of Windows and check the settings
• Be sure that the resolution is set for WQXGA (2560 x 1600) at 60Hz, or
WQUXGA (3840x2400 @33Hz vertical refresh rate) (not to the unsupported
XGA resolution)
• Reset the system
• Disconnect and reconnect the optical DVI cables
Be sure that at all times the cables are stored and used away from
liquid or dirt.
